摘要

由于太阳能的电流电压(I-V)和功率电压(P-V)随天气变化呈现非线性特性,因此如何提高太阳能的最大利用率是目前太阳能研究的热点之一。一般来说,已经引入了许多方法,称为太阳能最大功率点跟踪(MPPT)。本文研究了在数字信号处理器(DSP) TMS320F2812软件中实现的微扰观测(P&O)技术。该系统主要由直流升压变换器、西门子SP75太阳能模块和DSP软、硬件组成。给出了仿真和实验设置,并对结果进行了说明。

DSP-based maximum peak power tracker using P&O algorithm
One of the common research study on solar energy is on how to improve the maximum use of solar generated power because they exhibits a nonlinear current-voltage (I–V) and power-voltage (P-V) characteristics depends on the weather changes. Generally, many methods have been introduced, known as solar maximum power point tracking (MPPT). This paper presents a study on MPPT technique namely Perturbation and Observation (P&O) implemented in Digital Signal Processor (DSP) TMS320F2812 software. The proposed system mainly comprises a dc boost converter, Siemens SP75 solar modules and DSP software and hardware. Simulation and experimental setup together with the results are shown and explained.
